CLOSURE FOR CONTAINERS.

Application filed March 13, 1924. Serial No698,972.

T all whom it may concern:

Be it known that I, O'r'ro citizen of the German Republic, residing at Dresden, Germany, have invented certain new and useful Improvements in Closures for Containers, oi which the following is a specification.

This invention relates to a contrivance for closing sprinkling bottles and similar hollow vessels in which on the cap fired on the bottle neck a cover is rotatably mounted, the cap and the rotatable cover having both an eccentrically arranged outflow orifice which, registering the one with the other, permit the outflowing of the liquid but otherwise shut the same oil. In contrivances of known type a separate packing body is inserted between the cap and the cover, whereby the cost of manufacturing is increased. This arrangement does not absolutely prevent leakage. I V

The closing contrivance according tothe invention consists merely of the cap and of the cover, the packing being ensured by an elastic flap partly separated from the cover and connected with the same only by two strips situated both in one central axis. The cost of manufacturing of the closing contrivance is thus considerably decreased and the construction is much simplified, the packing being very reliable and last-in An embodiment of the invention is shown by way of example on the accompanying drawing in which:

Figs. 1 and 1 show contrivance, and

Figs. 2 and2 the corresponding cover in section and in plan view respectively.

Fig. 8 shows the two parts assembled.

The cap A, which is securely fixed on the bottle neck, has at the upper end a circular bead (Z on which the edge of the cover B is the cap of the closing fixed by being narrowed. In the cap A an orifice a is arranged and an orifice b in the GOTTSCHALK, a

cover 13, said orifices being eccentrical and adapted to be brought into register by rotating the cover B on the cap A. The rotation of the cover on the cap is limited by a stop of the cover engaging with an annular groove in the cap. WVhen the cover is in the one extreme position the orifices a and Z) register. 7

The orifice a is packed by means of an elastic flap 0 cut out of the cover B by stampin The elasticity of the flap is ensured by means of. two strips e connecting theflap with the cover. These strips istand perpendicularly to the line of symmetry of the cover (Fig. 2 The flap 0 covers in the other extreme position of the cover the orifice a and is securely pressed on the cover by the elasticity of the cover which is slightly vaulted whereby an air-tight closing of. the bottle neck is ensured. The packing pres-.

sure is exerted only at the point where it is really required, and the flap owing to its elasticity is capable to adapt itself accurate- 1y to the surface of the cap. The pressure produced in the manner described between the cap A and the cover B is quite sufficient 7 to secure the cover against accidental rotation but it is not strong enough to impede the rotatability of the cover.

I claim: 7

A contrivance for closing sprinkling bot- 7 tles and similar hollow vessels comprising in combination a cap securely fixed on the bottle neck and having an eccentric orifice in its top plate, a cover rotatably mounted on said cap and having an eccentric orifice, an

elastic flap stamped out or" saidcover and two oppositely situated strips connecting said flap with said cover.

In testimony whereof I affix my signature in presence of two witnesses.
